Detailed Explanation of the Key Techniques for Propagating Golden Privet (Ligustrum vicaryi) from Cuttings

I. Preparation of the cutting bed. First dig the cutting bed and firm the surrounding edges. Fill the bed with substrate in layers: spread 10 cm of cinder at the bottom layer to aid drainage, spread 10 cm of humus soil in the middle layer, and spread 5 cm of coarse sand on the top layer, then level the bed soil and set it aside. Finally, build an arched shed with bamboo strips and plastic.

II. Cutting treatment. Select one-year-old branches cut from greening plots and roadside green belts, cut them into cuttings about 15 cm long, and keep 1-2 leaves at the top of each cutting. Because privet has dense axillary buds and a relatively high survival rate, no chemical solution treatment is needed before insertion.

III. Inserting the cuttings. Insert the prepared cuttings immediately into the cutting bed to a depth of 1/2 the length of the cutting, and water them as they are inserted.

IV. Management after insertion. Strengthen management during the cutting period, supply water in a timely manner, and keep the bed moist. When the temperature inside the bed exceeds 25°C, ventilate and exchange the air on windless days.
